excellent knowledge of linux and unix systems in general
installation and tuning services and high-level applications such as LAMP, dns, postgres, oracle, squid, smtp, pop3, postfix, exim, cPanel/WHM, ISPmanager, DirectAdmin, Plesk, etc.
optimization, clustering, big data, high availability, failover
virtualization (VMware, KVM, Xen, OpenVZ, Proxmox Citrix)
knowledge of TCP/IP and the OSI model (vpn, port-forwarding, routing, BGP).
